When the tunneling phenomenon occurs at the metal-insulator contact barrier, as for the MIM structures, we are dealing with the Fowler-Nordheim field emission. In MIM structures we have to calculate the currents densities that go through. Unfortunately, the calculation methods currently used lead to values that get predictions of emission current density too low. The current density is calculated based on the transmission coefficient through the barrier, which is determined by solving the Schrödinger equation. One of the oldest and most efficient methods of solving the Schrödinger equation is the WKB method. This paper proposes the wavelet method for solving the 1D Schrödinger equation, that is: determining the wave function using the harmonic multiresolution analysis.","PeriodicalId":399638,"journal":{"name":"2013 8TH INTERNATIONAL SYMPOSIUM ON ADVANCED TOPICS IN ELECTRICAL ENGINEERING (ATEE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126187200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to assess the CFL's, which were made by ICPE there have been analyzed their main performances such as the maximum temperatures on the lamp and the plastic housing and the main technical characteristics: the power factor λ, the waveform THDI and the power consumption of the network.

Used more and more in modern medicine, high tech equipment is already popular in health care infrastructures and facilities. Interdisciplinary qualified personnel are expected to provide the innovative design, development and maintenance of such equipment and the technical assistance for therapy. A Master of Science program in the field of Medical Engineering started at University “Politehnica” of Bucharest more than ten years ago; it is offered to graduates of engineering, medical sciences, and other scientific tracks (physics, biology, informatics etc.). The main characteristic of the program is interdisciplinarity; education and genuine interprofessional experience are offered in a stimulating interactive academic environment. From the technical perspective, Electrical & Electronic Engineering plays a significant role in the scientific activities spectrum contributing to high performance technical outcomes for new medical technologies and modern equipment. In this paper we highlight the following issues: goals of the educational program, accredited curriculum, available resources, educational methods and professional competence expected from master studies graduates in medical engineering. Several particularities that individualize the educational program from other common master studies and the methods experienced here are also shown. The attraction for candidates and the professional satisfaction are assessed by some statistical data and comments.","PeriodicalId":399638,"journal":{"name":"2013 8TH INTERNATIONAL SYMPOSIUM ON ADVANCED TOPICS IN ELECTRICAL ENGINEERING (ATEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121058507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
